W'ATER-J'AGKETEDOOXTROLLIN G AND CHECK VALVE.

Specification of Letters Patent. Application filed March 14;. 1907- Sarial No. 362.321.

Patented March s, 1908.

To all whom itmay concern:

Be it known that I, FRED PEULEOKE, a citizen of the United States of America, and a resident of Chicago, county of Cook, State of Illinois, have invented certain new and.

useful Improvements in Water-Jacketed Controlling and Check Valves, of which the following isla specification.

The main. objects of this invention are to provide an improved form of regulating check valves particularly adapted to control the flow ofheated gases which would rapidly destroy valves of ordinary construction; to provide a valve which will be durable when used in the connection between the cylinder ofan internal combustion engine and a pressure tank which receives its charge from such cylinder and lprovides gas under pressure for operatingaw 'stle, emergency brake, or other fluid pressure driven apparatus which is auxiliary to the engine. These objects areaccomplished by the devices shown in the accompanying drawing in which:

Figure 1 is a diagram view showing a typical embodiment of the invention as apphed to a whistle. Fig. 2 is a sectional detail showin the construction of the water jacketed va ve.

In the drawings 1 designates the cylinder of an internal combustion engine; 2 is a pressure receiver or storage chamber adapted to hold a quantity of gas under pressure and communicating with the engine cylinder; 3 is a whistle representing a device auxiliary to the engine and having normally closed communication with the tank 2. The whistle is controlled by a suitable valve whose lever is indicated at 4:. a

The chamber 2 is connected with the clearance space at the top of the cylinder 1 by the pipe 5 and 5, provided with a combined regulating and check valve 6 adapted .to permit gas to flow from the cylinder to the chamber 2 and prevent the return flow of the gas from the chamber to the engine cylinder.

The valve 6 comprises a valve casing and an 'outer globular shell which entirely surrounds the valve casing and provides a suitable water chamber 8 having large capacity as compared with that of-the casing 7. The casing 7 has branch passages 10 and 11-disposed at right angles'to each other, and com-- munication between them is controlled by a needle valve 9. A ball check valve 12,seated within an enlargement ofthe passage 11 prevents a return flow of gas through the paswater""tliiough said casingjor ,coolingsai sage 1 1 The gas inlet 13 is connected with the pipe 5 and the outlet 14 is connected with the chamber 2by a section of pipe 5. Water is admitted to the jacket chamber 8 atthe inlet 15 which is connected to the water I jacket of the engine cylinder 1 by a A waste pipe 17 is connected to the out et18. By adjusting the needle valve 9 thepassage between it and its seat may be contracted to sufiicient extent to insure that the gases become cooled'to the desired de ree, bycontact with the comparatively col seat,'before' reaching the check valve. I p

The needle valve 9 is provided with a handle 19..) The plug 20 permits of accessto the check valve 12 and its seat.

The 0 eration of the device shown is as follows: pon each ignition of a charge the engine cylinder, the violent expansion of the gases will force a portion thereof through pipe 5, past the check valve 12, and-through pipe 5 to the reservoir. The check valve prevents the return flow of as when the pressurein the cylinder falls elow that of the chamber 2. In this manner the ressure of the gas withir. the chamber 2 be increased until the explosive pressure the cylinder is no longer suflicient' to open the:

the whistle or other device, the check valve 1 will again admit an additional charge of gas. The engine cylinder is provided'with the usual exhaust port (not shown) and 7 exhausts therethrough. 7

What I claim as my invention and desire to secure by Letters Patent, is:

1. In apparatus of the kind described, avalve casing having a gas passage provided with inlet and outlet connections, a regulating valve controllingf'the' flow of gas through said passage, a check valve for preventl'ng the backward flow of gas, said casing being formed with a water space surrounding both of said valves and 'having inlet and outlet connections for circulating water around said valves.

internal combustion engine, of a fluid storage chamber a connection between said cylinderafii stdrag'e chamber, a contracted passage in said connection, the length of said passage being considerabl greater than its width, a casing surrounding t ewallsof said contracted passage, and means for circulatin water through said casing for cooling said walls and thereby reducing the temperature of fluid flowing through said contracted passage, and a check valve between said contracted passa e and storage receptacle.

3. The com ination with the cylinder of an internal combustion engine, of a fluid stora e chamber, a connection between said cylin er and storagechamber, a contracted passage in said connection, a casing sur- I an internal combustion engine, of a storage rounding the walls of said contracted passage, means for circulating water through sa1d casing for cooling said walls and thereby reducing the temperature of fluid flowing through said contracted passage, and a check valve between said contracted passage and storage receptacle, and a regulating valve for adjusting the flow of fluid through said contracted passage.

4. The combination with the cylinder of an internal combustion engine, of a fluid storage chamber, a connection between said cylinder and storage chamber, a contracted passage in said connection, the length of said passage being considerably greater than its width, a casing surrounding the'walls of said contracted passage, and means for circulating walls and thereby reducing the temperature of fluid flowing through said contracted passage, and a check valve within said casing and located between said contracted passage and said storage chamber.

5. The combination of a casing having a gas inlet and a gas outlet, the walls of said casing being spaced away from'the walls of said passage and forming a jacket surround ing' the walls of saidpassage, a needle valve ex tending into said passage and adapted to control the flow of gas therethrough, and a check ,valve located between said needle valve and said outlet and adapted to prevent a return flow of gas through said passage, said casing having connections for circulating water around the walls of said passage.

6. The combination with the cylinder of chamber for fluid under pressure, a connection between said chamber and the 1nter1or of sald engine cyhnder, said connection 1ncluding a water acketed needle valve for r regulating the flow of gas through said connections and a water jacketed check valve adapted to prevent a return flow of' gas toward said engine cylinder and located between said needle valve and said chamber.

7. The combination with the cylinder of an internal combustion engine, of a storage chamber for fluid under pressure, a connection between said chamber and'the interior of said engine cylinder, said connection comprising a water jacketed needle valve for regulating the flow of gas through said connection, awater jacketed check valve adapted to prevent afreturn flow of gas toward said engine cylinder and located between said needle valve and said chamber.
